Description

TECHNICAL FIELD

[0001] The present application relates to the field of plastic recycling, and particularly relates to a plastic color master batch recycling device. BACKGROUND

[0002] The plastic color master batch is a high-concentration colorant made by uniformly loading excess pigments or dyes in a resin carrier. The basic components include pigments, carrier resins and dispersants. Through professional processing technology, the color master batch can ensure stable and uniform dispersion of pigments in the final plastic products, has the advantages of good coloring effect, convenient use, environmental protection and cleanliness, and is widely used in plastic extrusion, injection molding, film blowing and other molding processes.

[0003] In the production and recycling process of the color master batch, the strip-shaped residual material extruded by the extruder is generally collected, cooled in a cooling water tank, and then collected and dried. Then the residual material is crushed into small particles by a crusher, and finally the recycled material is sent into the extruder according to a certain proportion for recycling. This method aims to improve the utilization rate of raw materials, reduce production costs, and reduce the generation of industrial waste, which is a common recycling economy practice in the industry.

[0004] In use and observation, it is found that the residual material generated by the extruder is generally divided into two cases. One is the extrusion discontinuity caused by the uneven plasticization of the material itself, or the excessive viscosity of the melt caused by the formula, and the other is the active debugging and discharging for the purpose of ensuring product quality. The first case will cause the residual material to fall into the cooling water tank, increase the subsequent manual salvage operation, and further cause the inconvenience of color master batch recycling operation.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0031] The specific embodiments are given below.

[0032] Please refer to Figures 1 to 8As shown, the plastic color master batch recycling device comprises a water tank 1, which is suitable for a color master batch extruder. The color master batch extruder comprises an extruder body 12, and the die outlet of the extruder body 12 extends directly above the water tank 1. A plurality of guide wheels 110 are arranged in the water tank 1 for guiding the single filaments produced by the extruder body 12. Three conveying rollers 13 are arranged in the inner wall of one side of the water tank 1 in sequence along the transverse direction. A first power source is arranged on one side of the water tank 1 for driving one of the conveying rollers 13 to rotate. A conveying belt 14 is arranged on the outer wall of the three conveying rollers 13. A plurality of push plates 15 are fixedly connected to the surface of the conveying belt 14. An opening is arranged on the side of the water tank 1 close to the conveying roller 13, and a sliding plate 17 is fixedly connected to the opening. A collection assembly is arranged at the end of the sliding plate 17 for recycling residual materials. A guide plate 16 is fixedly connected to the inner wall of the water tank 1, and the guide plate 16 is arranged to be inclined towards the opening. A water inlet 18 is arranged on one side of the water tank 1, and a water supply device is connected to the end of the water inlet 18. A water level line 19 is arranged on the inner wall of the water tank 1 for reference of the water level in the water tank 1.

[0033] The extruder body 12 can extrude molten materials into filaments through a die. The extruded filaments can be manually guided through the guide wheels 110 in the water tank 1. The filaments can be cooled and shaped by the cooling water in the water tank 1. The cooled filaments can be conveyed to a pelletizer by the traction assembly for granulation. The working principle of the traction assembly, the pelletizer, and the float ball valve can be referred to Figure 3 In addition, the water level in the water tank 1 is flush with the water level line 19 to ensure the water level required for subsequent overflow separation of residual materials. The automatic control of the water level can be realized by arranging a float ball valve at the water inlet 18. The structures and working principles of the traction assembly, the pelletizer, and the float ball valve are mature existing technologies, and therefore are not described and illustrated here.

[0034] When the raw materials appear to be caked or over-sticky, the organization will separate in the extruder body 12, resulting in the extruder body 12 die outlet material intermittent and residual material, these residual material can fall into the water and float to the water surface, when the extruder body 12 works, the first power source is also started and drives the directly connected conveying roller 13 to rotate, the first power source is preferably a speed reducer motor, the conveying roller 13 can drive the conveying belt 14 with a surface sleeve to rotate away from the extruder body 12, to drive the push plate 15 to rotate, the push plate 15 can continuously push the residual material floating on the water surface when rotating, and the push plate 15 can disturb the water flow in the water tank 1 when rotating, so that the upper water flow flows away from the extruder body 12, so that the residual material flows to the guide plate 16 under the cooperation of the push plate 15 and the water flow, since the guide plate 16 is inclined to the opening, the residual material will fall into the chute 17 in the opening under the action of accumulation and overflow, and then fall into the collection assembly, since the water level in the water tank 1 is flush with the water level line 19, it can ensure that the residual material can stably enter the chute 17 when it is accumulated and overflowed, in addition, when the water tank 1 normally cools the monofilament, since the first power source is also in the starting state, i.e. the push plate 15 can disturb the water layer in the water tank 1, the temperature gradient of the cooling water in the water tank 1 can be broken, and the cooling effect of the cooling water on the monofilament can be improved, it is worth mentioning that the conveying roller 13 and the inner wall of the water tank 1 leave a certain gap, which can provide space for the initial manual pulling operation of the monofilament; through the cooperation of the push plate 15, the guide plate 16 and the chute 17, the floating residual material in the water tank 1 can be pushed and guided into the collection assembly, so as to realize the automatic separation of the residual material and simplify the complicated operation of manually fishing the residual material in the water tank 1.

[0035] Please refer to Figures 1 to 4 As shown in the figure, the bottom of the water tank 1 is provided with a material falling groove 2, and the inner wall of the material falling groove 2 is Y-shaped; the end of the material falling groove 2 is communicated with a conveying pipe 23; the conveying pipe 23 is provided with a valve for controlling opening and closing; the end of the conveying pipe 23 is also provided with a collection assembly; the middle conveying roller 13 is higher than the other two conveying rollers 13; a screw conveyor 22 is rotatably arranged in the material falling groove 2; one side of the material falling groove 2 is provided with a second power source for driving the screw conveyor 22 to rotate;

[0036] When the extruder body 12 is stopped and debugged, the accumulated material in the extruder body 12 needs to be discharged, and the residual material extruded from the extruder body 12 can be sheared by manual operation during the discharging process. The sheared residual material can be divided into two types according to the density, one is the residual material floating on the water surface, such as polyolefin, with a density of about 0.91-0.93 g / cm 3 , which is most of the color master batch material, and the other is the residual material that can be deposited in water, such as polyvinyl chloride, with a density of about 1.3-1.45 g / cm 3, The floating residual materials can be separated naturally in the above manner, while the deposited residual materials will fall onto the surface of the conveying belt 14, and finally the deposited residual materials can be conveyed by the conveying belt 14 to the discharge chute 2. During the debugging process, the second power source, preferably a speed reducer motor, can be started to drive the directly connected auger 22 to rotate, and the auger 22 can screw convey the deposited residual materials, so that the deposited residual materials can be discharged together with the cooling water from the open valve conveying pipe 23 into the collection assembly; through the cooperation of the auger 22 and the conveying pipe 23, the deposited residual materials with a larger density can be separated and recovered, so as to improve the adaptability of the device to different types of color master batch residual materials during recovery.

[0037] Please refer to Figure 2 and Figure 4 , the collection assembly includes a box body 3; the box body 3 is detachably provided with a mesh frame 32, and the bottom of the mesh frame 32 is provided with a plurality of holes; the inner wall of the mesh frame 32 is fixedly connected with a lug plate 33, and the lug plate 33 is correspondingly provided at the end of the conveying pipe 23 and the chute 17; the box body 3 at the bottom of the conveying pipe 23 is in communication with the water tank 1 through the water pump assembly;

[0038] The residual materials can be discharged into the mesh frame 32 through the conveying pipe 23 or the chute 17, and the mesh frame 32 and the box body 3 can separate and collect the residual materials and water. Since the lug plate 33 is provided at the discharge position of the conveying pipe 23 and the chute 17, the lug plate 33 can forcibly guide the residual materials to reduce the accumulation of the residual materials at the discharge position. In addition, the water collected by the box body 3 at the bottom of the chute 17 is mostly the attached water on the surface of the residual materials, which can be ignored. The box body 3 at the bottom of the conveying pipe 23 collects the waste water discharged from the water tank 1, so the box body 3 at the bottom of the conveying pipe 23 can re-convey the waste water to the water tank 1 through the water pump assembly. In addition, considering the re-chilling of the waste water, a refrigeration assembly can be arranged in the box body 3 to ensure the cooling performance of the cooling water in the water tank 1.

[0039] Please refer to Figure 1 , Figures 5 to 8 , the other side of the water tank 1 is fixedly connected with a rack 4; the bottom of the rack 4 is engaged with a gear 43; the side of the water tank 1 close to the rack 4 is slidingly provided with a sliding plate 42; the inner wall of the gear 43 and the sliding plate 42 is rotatably connected, and one side of the sliding plate 42 is provided with a third power source for driving the gear 43 to rotate; the other side of the sliding plate 42 is fixedly connected with a cleaning plate 44 at the bottom, and the cleaning plate 44 is provided in a semicircular shape; the top of the cleaning plate 44 is communicated with an air inlet pipe 45, and the end of the air inlet pipe 45 is communicated with a gas supply device; one side of the cleaning plate 44 is provided with a plurality of holes, and a one-way valve assembly is arranged in the hole;

[0040] In the recycling of floating scraps, the third power source, preferably an electric motor, can be controlled to drive the directly connected gear 43 to rotate, and the gear 43 can be engaged with the rack 4, so that the sliding plate 42 can slide transversely along the water tank 1 under the action of the engaged power. In the process, the gas supply device connected to the end of the air inlet pipe 45 can be started, which can be a gas pump or a high-pressure gas cylinder. The compressed gas flow is driven to enter the cleaning plate 44 through the air inlet pipe 45, and is discharged from the side hole of the cleaning plate 44, which is arranged towards the guide plate 16. That is, the cleaning plate 44 will approach or move away from the guide plate 16 as the sliding plate 42 moves transversely. During the approach to the guide plate 16, the high-pressure gas sprayed from one side of the cleaning plate 44 can blow the residual material in the reserved operating space in the water tank 1 to the upper side of the conveying belt 14, and forcibly blow the residual material accumulated at the opening of the water tank 1. During the process of moving away from the guide plate 16, the arc-shaped arrangement on the other side of the cleaning plate 44 can push the contacted residual material to the upper side of the conveying belt 14 under the arc-shaped guide action. Through the cooperation of the gas blowing on one side of the cleaning plate 44 and the extrusion on the other side, the floating material existing on the manual operation side of the water tank 1 can be forcibly adjusted to the upper side of the conveying belt 14, which is convenient for the subsequent sliding plate 17 to drop the floating residual material.

[0041] Please refer to Figure 7 As shown in the drawings, the inner wall of the cleaning plate 44 is fixedly connected with a volute 5; the volute 5 and the end of the air inlet pipe 45 are connected through a pipeline, and one side of the volute 5 is provided with an exhaust hole; the inner wall of the volute 5 is rotatably connected with a turbine 52 at the top; the bottom of the turbine 52 is fixedly connected with a rotating shaft 53, and the rotating shaft 53 penetrates and is rotatably connected with the volute 5 and the cleaning plate 44; the rotating shaft 53 is perforated in the volute 5, and a plurality of air distribution rings 54 are fixedly connected to the outer side of the cleaning plate 44; the outer wall of the air distribution ring 54 is perforated, and a one-way valve assembly is also arranged in the hole;

[0042] The compressed gas flow can enter the volute 5 through the air inlet pipe 45 and be discharged from one side to the cleaning plate 44, and the turbine 52 can rotate under the action of the gas flow. The rotating shaft 53 and the air distribution ring 54 can rotate with the turbine 52, and at the same time, part of the compressed gas flow in the volute 5 can enter the volute 5 through the hole at the top of the volute 5 and be discharged from the circular hole of the air distribution ring 54. At this time, the air distribution ring 54 can be in a state of autorotation and spray gas into the water tank 1 during the movement of the cleaning plate 44. A refrigeration assembly is arranged at the gas source of the gas supply device, so that the air distribution ring 54 can spray cold gas. The cold gas sprayed by the air distribution ring 54 can cool the water body, thereby improving the cooling efficiency of the water body on the single wire.

[0043] Please refer to Figure 8As shown, the one-way valve assembly comprises a fixed plate 6; the fixed plate 6 is fixedly arranged inside the cleaning plate 44 and the air distribution ring 54 respectively; a sliding rod 62 is slidably arranged on the fixed plate 6; a spring is installed between one end of the sliding rod 62 and the fixed plate 6, and the other end is sequentially fixedly connected with a conical part 63 and a plug 64, and the plug 64 is used for plugging the hole;

[0044] In the initial state, the plug 64 is in a plugging state in the circular hole of the cleaning plate 44 and the air distribution ring 54, and here, the cleaning plate 44 is taken as an example. When the gas supply device is started, the sliding rod 62 can be pushed under the action of gas pressure and the spring is in a compressed state. In the process, the sliding rod 62 can slide along the fixed plate 6, and at the same time, the plug 64 and the conical part 63 slide out of the cleaning plate 44. In the sliding process of the conical part 63 along the hole, the communication area of the cleaning plate 44 with the outside world gradually increases, ensuring that the flow area of the gas flow is continuously and smoothly changed, ensuring the smooth release of the gas pressure, and improving the stability of the one-way valve assembly during operation.

[0045] Please refer to Figure 8 As shown, the end of the plug 64 is fixedly connected with a ball 7;

[0046] By arranging the ball 7, on the one hand, the ball 7 can limit the end of the plug 64 to reduce the over-resetting of the plug 64 and the sliding rod 62 with the spring, and on the other hand, the arc structure on the surface of the ball 7 can diffuse the compressed gas flow after being sprayed out of the hole, expanding the flow direction of the cooling gas flow.

[0047] Please refer to Figure 6 and Figure 7 As shown, the bottom of the cleaning plate 44 is fixedly connected with a pair of water distribution plates 8; the water distribution plates 8 are evenly distributed on both sides of the rotating shaft 53, and the water distribution plates 8 are V-shaped structures;

[0048] By arranging the water distribution plates 8, the pair of water distribution plates 8 can enclose the rotating shaft 53. In the process of transversely moving the cleaning plate 44 along with the sliding plate 42, the water distribution plates 8 can guide the water to smoothly flow over the surface of the water distribution plates 8, reducing the resistance between the rotating shaft 53 and the water when the rotating shaft 53 moves along with the cleaning plate 44, and further improving the utilization rate of the compressed gas flow power by the turbine 52.

[0049] Please refer to Figure 7 As shown, a plurality of grooves 9 are equidistantly arranged on the water distribution plate 8; the grooves 9 are parallel to the sliding plate 42;

[0050] Since the grooves 9 and the sliding plate 42 are parallel to the moving direction, the flow of the water in the vertical direction of the grooves 9 can be inhibited, and thus the stability of the water flow can be ensured.

[0051] Please refer to Figure 3 As shown, the push plate 15 comprises a straight line part and a curved part, and the straight line part is in a fixed connection relationship with the conveying belt 14;

[0052] By additionally setting the curve part on the push plate 15, the straight line part is used for lengthening the structure, and the curve part is used for pushing the floating residual materials on the water surface, so that the residual materials first contact the middle part of the curve part and then contact the two sides of the curve part, so that the push plate 15 can more gently guide the residual materials to flow forward, reducing the local accumulation and bridging.

[0053] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
